Logon VB script does not map network drives under Vista

I just finished a new SBS 2003 R2 roll-out with the majority of the computers running Windows Vista Business and Ultimate.

The rollout finished pretty much without any major problems. After all the computers joined the domain I decided to take a VB script I use to map network drives and I adjusted it to meet the client’s needs. I added the script to the Default Domain Policy GPO. Unfortunately the drives weren’t mapped to the Vista clients.

After spending some time researching the issue, I came across the solution in the form of a Microsoft Knowledge Base article http://support.microsoft.com/kb/937624

The problem was related to the Vista UAC and the article describes the modifications to the registry that need to be done in order to solve it.
